I'm using LS 1.90.
I've enabled JS and successfully ran the test script (custom template).
I've cut and paste the workaround JS script in the custom template (at the beginning). Didn't modify anything.
I've followed the instructions an ran the survey for testing but:
- the multiple choice questions are not hidden
- the ranking filter doesn't work
I'm tried question by question and group by group.
If you like I can supply you a login.

Perfect!!!! It works. Even when creating more groups and referring to the first. Hopefully last question:) The last group I've created is a multiple numeric (sum to 100). Used same method. The hidden question is hidden but the list is the complete list again. Can that to?

question 5.
If you have enough of my questions I understand:)
